A table of critical values is presented for use with Chacko's ordered alternatives test for the analysis of variance. (Author/JKS)

Many researchers assume that unequal cell frequencies in analysis of variance (ANOVA) designs result from poor planning. However, there are several valid reasons why one might have to analyze an unequal-n data matrix. The present study reviewed four categories of methods for treating unequal-n matrices by ANOVA: (a) unaltered data (least-squares…

The results of an investigation into some special cases of the general "orthomax" formulation are presented. In particular, the effects of manipulating a parameter in this formulation on various aspects of factor solutions are identified through the use of four sets of data, varying considerably in size, and reliability and factorial complexity of…

Points out that 108 studies in the first 25 volumes of AV Communication Review used univariate analysis of variance to test experimental hypotheses, and suggests that researchers include omega-squared values in their reports to permit estimation of the relationship between x and y variables, and correlation data for comparing studies.

The language skills category of objectives of the Appalachia Preschool Education Program as measured by the Illinois Test of Psycholinguistic Abilities (ITPA), is discussed. The point is made that one of the difficulties associated with evaluating language development is the loose fit between available theoretical and operational definitions of…

This paper is an ardent plea for simplifying experimental design and the associated statistics. The emphasis is on design itself. Traditional designs from simple to complex and reviewed and the simplest, most basic ways of handling the data are presented. Design is stressed in such a way that simple statistics follow. The intactness of…

This report covers Phase II of a two-phase project concerned with the development of new measures of cognitive variables in elementary school children. The four tasks undertaken in Phase II were: (1) prepare, revise and describe instruments designed to measure the cognitive variables categorized as concept formation, language development, logical…

Formulae and graphs are presented allowing computation of the variances of three prototypical distributions over a finite number of categories. The uses of the variances of the maximum variance distribution, the uniform distribution and a unimodal triangular distribution to make inferences about distribution shapes are shown in several examples.…

Even the application of such mainstays of the institutional researcher's statistical tool kit as the t test and ANOVA is not always as straightforward as it seems. The researcher must first check to see that the underlying methodological and statistical assumptions are being met. (Author)

Two variables related to decision making and goal persistence, self-concept and locus of control are examined. Factor analysis and reliability data for these scales are discussed, and the use of short instruments within the context of a larger survey to examine such educational variables is explained.

A summary and comparison of the statistical analysis and results of the first three GUME research projects investigating foreign language teaching methods are presented in this report. The methods investigated are the habit-formation or implicit theory and the cognitive-code learning or explicit theory with either source-language or…

A one-way analysis of variance was used to assess the effects of imposed (picture) and induced (play) imagery on the aural language comprehension of 80 kindergarten children who were randomly assigned to two treatment and two control conditions. No significant differences in recall were found. (Author/JD)

This monograph contains the second section, operations at the variable level, of a report of studies done in Helsinki, Finland, describing school achievement in terms of ability, trait, situational, and background variables. The report (1) investigates the structure of school achievement, (2) describes school achievement in terms of selected…

Possible differences in rater confidence were investigated among raters whose primary role with the ratee was either professorial or administrative or that of an employer. As hypothesized, significant differences were found among the groups and among types of performance rated. (LBH)
